A short movie made from the images taken by Terrain Mapping Camera (TMC) of Chandrayaan-1 as the spacecraft flew over the area near the South polar region of moon. The Terrain Mapping Camera,built by ISRO’s Space Applications Centre(SAC) of Ahmedabad, is taking excellent pictures of Moon’s surface from Chandrayaan-1’s 100 km high orbit from the Lunar surface.

These two are close up pictures of the moon’s surface taken by Moon Impact Probe (MIP) on November 14, 2008 as it approached it after separating from Chandrayaan-1 spacecraft. Please note that these pictures are reproduced as received.

This is the picture of moon’s surface taken from lunar orbit by Chandrayaan-1 spacecraft’s Terrain Mapping Camera (TMC) on November 13, 2008. Taken over the equatorial region of the moon, the picture shows the uneven surface of the moon with numerous craters. On the lower left, part of the Torricelli crater is seen.

Taken over the polar region of the moon, the picture shows many large and numerous small craters. The bright terrain on the lower left is the rim of 117 km wide Moretus crater.

India on Friday became the fourth nation to have its flag flying on the Moon’s surface when Chandrayaan-1’s Moon Impact Probe device, – which has the Indian Tricolour painted on it – touched down. The 35-kilo payload crash-landed on the lunar surface at around 2030 hrs IST. The MIP has started sending its first signals to the satellite.

It also contains equipment which will help scientists design a lunar lander or rover for the upcoming Chandrayaan-2 mission.

There’s a lot tucked away inside the MIP. There’s a device to constantly check it’s height as it falls, another to check what the air on the moon is made of and even a video camera to photograph the moon from close range. Those photographs will help ISRO decide where to land India’s first moon rover, a few years from now. The MIP also has the Indian flag painted on its sides a Sanskrit shloka as well.

Artist’s concept of the star Fomalhaut and the Jupiter-type planet that the Hubble Space Telescope observed. A ring of debris appears to surround Fomalhaut as well.

Estimated to be no more than three times Jupiter’s mass, the planet, called Fomalhaut b, orbits the bright southern star Fomalhaut, located 25 light-years away in the constellation Piscis Australis, or the “Southern Fish.”

The planet is brighter than expected for an object of three Jupiter masses. One possibility is that it has a Saturn-like ring of ice and dust reflecting starlight. The ring might eventually coalesce to form moons. The ring’s estimated size is comparable to the region around Jupiter and its four largest orbiting satellites.

Future observations will attempt to see the planet in infrared light and will look for evidence of water vapor clouds in the atmosphere. This would yield clues to the evolution of a comparatively newborn 100-million-year-old planet. Astrometric measurements of the planet’s orbit will provide enough precision to yield an accurate mass.

The first orbit reduction manoeuvre of Chandrayaan-1 spacecraft which is orbiting the moon, was successfully performed on November 9, 2008 , night. As part of that manoeuvre which began at 20:03 IST, the 440 Newton liquid engine of the spacecraft was fired for about 57 seconds. With this, the nearest point of Chandrayaan-1’s orbit (periselene) from the moon’s surface was reduced from 504 km to 200 km while the farthest point (aposelene) remained unchanged at 7,502 km. In this elliptical orbit, Chandrayaan-1 takes about ten and a half hours to circle the moon once.

The fifth and final orbit raising manoeuvre of Chandrayaan-1 spacecraft was successfully carried out today (November 4, 2008) morning at 04:56 am IST. During this manoeuvre, the spacecraft’s 440 Newton liquid engine was fired for about two and a half minutes.With this, Chandrayaan-1 entered the Lunar Transfer Trajectory with an apogee (farthest point to Earth) of about 380,000 km (three lakh eighty thousand km).

The health of the spacecraft is being continuously monitored from the Spacecraft Control Centre at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bangalore with support from Indian Deep Space Network (IDSN) antennas at Byalalu. Since its launch on October 22 by PSLV-C11, all systems onboard Chandrayaan-1 spacecraft are performing normally. Chandrayaan-1 will approach the Moon on November 8, 2008 and the spacecraft’s liquid engine will be fired again to insert the spacecraft into lunar orbit.
